For the most part, this is identical to Thorped's design as I reverse engineered it. Admittedly it is 3mm narrower than his. Reason for this remix is because the original front foot did not fit my printer, but that could actually have been a bad slicing job. See here for details: http://www.thingiverse.com/make:144716 Foot inserts to be printed in flexible filament. (I don't have any, so I am waiting on a friend.) When printing, rotate the part by 90deg so that it is orientated in the same configuration as you would install it in. Printer is 95mm wide and front and rear fits nice and snug, really snug. I've installed the foot inserts now and they work like a charm. I really had to force them in, so as a result I'll alter the dimensions slightly for an easier fit.I printed mine at a 0.2mm layer height and 3 shells. And I think an infill of 30%.
